Filed: 1959-07-08
Abstract: 928,535. Valves. K. PARR. July 8, 1959 [July 10, 1958; July 11, 1958], No. 23507/59. Class 135. [Also in Group XIII] A vacuum relief valve 1, Fig. 1, has a chamber 2 connected by a pipe 3 to the outlet 4 of a hot-water storage tank 5 and a part 6 communicating with atmosphere. In the chamber 2, Fig. 2, is a flexible diaphragm 9 on a supporting plate 10, which diaphragm is loaded by a spring or weight 12 on to an adjustable annular seat 11 which co-operates with a diaphragm orifice 13. When the chamber 2 is subjected to pressure the diaphragm is urged thereby on to the seat 11. Application of vacuum to the chamber 2 causes the atmospheric pressure below the diaphragm 9 to firstly lift the plate 10 and then the diaphragm; the latter will be reseated by the weight when the pressure has been equalized. An auxiliary valve 15 is provided to increase the speed with which the diaphragm seats, which valve is a rectangular plate of thin sheet metal of low inertia that is guided by a stem extension of the seat 11. Passage of air to relieve a vacuum lifts the auxiliary valve 15 from its seat on the weight 12; when the pressure is equalized on both sides of the diaphragm 9 the valve 15 immediately falls to close the orifice 13. The relief valve 1 is combined with a pressureregulating valve 19 in the water supply to the tank 5, Fig. 1, both having a common atmospheric outlet 20. The seat 11, Fig. 2, is formed with a nut 21 on a screw 22 whereby the setting of the loading spring 23 of the regulating valve 19 is adjusted. A check valve 24 is disposed between the tank inlet and the outlet 4. Specification 832,201 is referred to.

Filed: 1966-05-26
Abstract: 1,186,188. Automatic phase control. ELECTRIC & MUSICAL INDUSTRIES Ltd. 26 May, 1967 [26 May, 1966], No. 23607/66. Heading H3A. A system for providing advanced line drive pulses for a remote television signal generator is provided with a control circuit which adjusts the timing of the advanced pulses in dependence on the length of cable between the remote and central apparatus. The control circuit includes a source of line drive pulses 2 which triggers the advanced pulse generator 3 to produce pulses advanced by a time 2d where d is the delay down the cable 5 to the remote apparatus. The incident pulses ,Fig. 2(b) at the cable input are added to the reflected pulses to produce composite pulses, Fig. 2(c) which are limited at 6, to produce pulses, Fig. 2(d), and then differentiated at 7 to produce pulses 2(e) corresponding to the leading edge of the reflected pulses. The input line drive pulses, Fig. 2(a) are similarly differentiated at 8 to produce pulses, Fig. 2(f) corresponding to the rear edge of the input pulses. The resulting pulses 2(e), 2(f) are used to trigger a bi-stable circuit 9. The output from the bi-stable circuit Fig. 2(g) is added to the input signal, Fig. 2(a), to produce positive or negative pulses depending on whether the advance produced in circuit 3 is greater or smaller than required. These pulses are then integrated at 12 and used to adjust the advance pulse generator 3. A suitable integrator is described, Fig. 3 (not shown).

Title: Improvements in and relating to electric arc welding apparatus
IPC: B23K9/067
Filed: 1956-08-01
Abstract: 794,687. Control systems for welding arcs; exciting dynamos. GENERAL ELECTRIC CO. Aug. 1, 1956 [Aug. 3, 1955], No. 23748/56. Classes 35 and 38 (4). Electric arc welding apparatus of the kind which operates with a self-regulating are supplied from a power source having a rising voltampere characteristic is provided with means whereby when a welding operation is begun the voltage and ampere values are set relatively high to strike an arc after which the values are reduced to continue the welding operation. The welding apparatus comprises a tool through which a welding electrode 6 is fed to the work 8 at high speed by a set of motor-driven feed-rolls 7, the weld taking place in an inert shielding medium. The power source comprises a split pole type of generator 20 having main polepieces 21, 22 operating at saturation to produce a constant voltage between main brush 28 and auxiliary brush 30 whilst unsaturated crosspolepieces 23, 24 produce a variable voltage between another main brush 29 and the auxiliary brush 30. Polepieces 25, 26 form commutating poles. To initiate a welding operation the electrode 6 is fed on to the work 8 to produce an arc, the voltage across which being that produced by the generator 20 with the field windings 35, 36 on the cross-polepieces 23, 24 aiding the field windings 38, 39 on these poles and the field windings 33, 34 on the main polepieces 21, 22. The windings 35, 36 are connected across the brushes 28, 30 by way of contacts 43, 48 on a field reversing relay 37 and a field setting rheostat 47. When an arc is struck a relay 54 is energized by current flowing through its operating coil 53, thereby closing its contacts 55 to energize the operating coil 56 of the relay 37 after a delay period set by a delay mechanism 56. The current direction through the field windings 35, 36 is now reversed, the circuit including contacts 59, 60 of the relay 37 and a field setting rheostat 62. The fields 35, 36 now oppose the fields 33, 34, 38, 39, thereby reducing the values of voltage and amperage applied to the weld. The changeover operation may be manually made or eliminated by means of a switch 63. The relay 54 may have a time delay on its return operation in order that it may not be responsive to transient interruptions in welding current. Alternatively the power source may comprise static apparatus having the necessary rising volt-ampere characteristics. Specification 159,374, [Class 35], is referred to.
